Tierney, 18, started for Celtic on the opening day of the Scottish Premiership season against Ross County, and played 60 minutes in an impressive performance.

Now, Tierney has penned a new four-year deal with the Bhoys, committing his future to the club having broken into the first team under Ronny Deila.

Speaking to the club's official website, Tierney admitted the faith shown by manager Deila was a factor in his decision to stay at Celtic Park for the foreseeable future, praising the Norwegian's philosophy.

"I’m delighted. I have been here 11 years already so to get a good contract for another few years at least is fantastic, and I’m happy to commit my future to the club I love," said Tierney.

"He put faith in me, because an 18-year-old starting on Flag Day doesn’t happen often," he added of Deila. "I have a lot to thank him for and all I can do is repay his faith in me. The way he wants the full-backs to play is how I like to play, getting up and down during the game and putting crosses in, so it’s good that his philosophy suits my style," he added.

Celtic have been searching for a left back for most of the summer, with first choice Emilio Izaguirre turning in a number of disappointing displays in 2015.

The Honduran needs competition at left back, and whilst Celtic haven't been able to bring in a new signing at the position, there will now be a hope that Tierney can be their solution - and stop Deila from having to spend money on a new signing.

With his future now at Celtic, Tierney can push on and bid for regular first team football, proving the Bhoys were right to give him a new contract in the process.
